Abstract
A magnetic tape apparatus is disclosed in which the tape is held stationary on the surface of a drum while the drum is rotated at a high velocity, thereby providing an air bearing for supporting the tape adjacent a rotating recording head. The tape is spaced from the drum because of an air bearing. To minimize the gap between drum and tape, grooves or notches are formed in the transducer head to cause the tape to cup or deflect down toward the head in the area of the transducer. The transducer heads in a multiple transducer arrangement are especially mounted on a parallelogram-shaped brace arrangement to eliminate undesirable lateral deflection of the heads during recording.
